The judge shall appoint an attorney to appear for and protect the
rights of any party or parties in interest who are unknown, or whose residence
is unknown and who has not appeared in the proceeding by an attorney or agent.
The State Treasurer as custodian of the Escheat Fund shall be notified of the
appointment of such an attorney. The judge shall appoint guardians ad litem for
such parties as are infants, incompetents, or other parties who may be under a
disability, and without general guardian, and the judge shall have the
authority to make such additional parties as are necessary to the complete
determination of the proceeding.

Upon his own motion, or upon motion of any of the parties the judge
may, in his discretion, continue the cause until the project is completed or
until such earlier time as, in the opinion of the judge, the effect of
condemnation upon said property may be determined. The motion may be heard at a
hearing pursuant to G.S. 40A-47 or upon the coming on of the cause for trial,
and shall be granted upon a proper showing that the effect of condemnation upon
the subject property cannot presently be determined. (1981, c. 919, s. 1.)
